Fruit tree growth cycle experienced growth, initial results, Sheng fruit, aging and update metabolic processes, different stage age physiological characteristics and nutritional requirements has certain difference. Young Young fruit is mainly the development and expansion of the root crown, with full accumulation of tree nutrient. During this period the growth of small amount, amount of fertilizer is not much, but sensitive to fertilizer. This stage of malnutrition, even after the double fertilization is also difficult to make up. Applying sufficient fertilizer phosphate fertilizer, nitrogen and potassium is early, early fruit yield results of one of the key measures. Early results No results or results in the beginning, because the root cap continues to expand, to maintain relatively strong growth, nitrogen fertilizer should be accounted for a larger proportion. During this period, continue to expand the crown and promote flower bud differentiation, increasing the phosphorus, potassium fertilizer should be in nitrogen based on. The middle Adult tree fruiting period, fertilization is the main purpose of high quality and high yield, improve the value of the goods. Due to the results and years of flower bud differentiation, should increase phosphorus, potassium, calcium fertilizer proportion, so fertilization to pay attention to nitrogen, phosphorus, potassium and calcium with, especially improve the proportion of potash fertilizer. The results of the full fruit period After full fruit tree body gradually aging and old age should be more nitrogen fertilizer, the proportion of nitrogen fertilizer should be with trees, to promote rejuvenation, maintain Sheng fruit is not bad. Thus, different fruit growth period of fertilizer with different ratio requirements, only the proper fertilization can let fruit vigorous growth, achieving the purpose of high quality and yield.
